Aeronautics Days, 19 th – 21 st June 2006 Introduction (1/3) • Automatic Dependent Surveillance – Broadcast (ADS-B) – ADS-B allows aircraft to broadcast identification, position, velocity, intent over ranges ~ 100 NM – ADS-B ground receivers enhance information for air traffic controllers – ADS-B technology invented 1980s. Now 40% of flights in Europe ADS-B Receiver equipped with ADS-B Mode S ground-station extended squitter of which half broadcasting position
Aeronautics Days, 19 th – 21 st June 2006 Introduction (2/3) • Airborne Separation Assistance System (ASAS) applications – 1983 “Analysis of in-trail following dynamics of Cockpit Display of Traffic Information (CDTI)”, Sorensen & Goka, NASA – 1994 Term “ASAS” introduced by CENA, France – 2001: Principles of operation of ASAS, FAA/EUROCONTROL – 2002: First package of ground surveillance and airborne surveillance applications defined, EUROCONTROL, European Commission
Aeronautics Days, 19 th – 21 st June 2006 Introduction (3/3) • ASAS Thematic Network 2 – Sponsored by European Commission Directorate General Research 6 th Framework – Three year project from April 2005 – Aim: to accelerate the application of ASAS operations in European Airspace taking into account global applicability in order to increase airspace capacity and safety. – Managed by consortium: BAE Systems, ENAV, LFV, NLR, Thales ATM & Thales Avionics, EUROCONTROL (leader)
Aeronautics Days, 19 th – 21 st June 2006 Objectives • 5 ASAS workshops & final seminar – Malmo (Oct 2005), Rome (Apr 2006) – Glasgow (Sep 2006), Amsterdam (2007) • Web-based ASAS related documentation • Annual assessment of the maturity of global ADS-B/ASAS applications by ASAS-TN2 partners – Deliverables: Report ”ASAS application maturity assessment” by March 2006, updated 2007 & 2008
Aeronautics Days, 19 th – 21 st June 2006 Method (1/3) • 17 ASAS applications in clusters – ADS-B surveillance – Airborne traffic situational awareness – ASAS spacing – ASAS separation – ASAS self-separation • 12 ASAS specialists from: BAE systems (UK), ENAV (Italy), LFV (Sweden), NLR (The Netherlands), Thales ATM (France), Thales Avionics (France) and EUROCONTROL
Aeronautics Days, 19 th – 21 st June 2006 Method (2/3) • Maturity metrics scale 0 to 4: – Operational concepts – Benefits and constraints – Safety assessment – Procedures and human factors – Systems, HMI and technology – Transition issues • Results reviewed by 9 selected peers from US (e.g. pilot working for Boeing) and Europe (e.g. EUROCAE)
Aeronautics Days, 19 th – 21 st June 2006 Method (3/3) Example metric - Operational concept 1 = Problem statement, identify solutions, concept generation (concept of operations) 2 = Preliminary Operational Concept Description (R&D Operational Service and Environment Description (OSED)) 3 = Draft Requirements Focus Group (RFG) OSED in development (e.g. from R&D OSEDs, trials and experiments, initial OSED) – mature and in review. 4 = Consolidated OSED - Published
Aeronautics Days, 19 th – 21 st June 2006 Results (1/5) – relatively mature Air Traffic Control surveillance in non-radar areas (ADS-B surveillance) • Objective : to provide ATC surveillance in non-radar areas e.g. remote areas, offshore, operation areas, any continental areas and certain oceanic areas, which, due to traffic level or cost of equipment could not justify installation of radars. • Benefits: – Surveillance with accurate position and track prediction (accuracy does not vary with range and bearing) – Controller can provide radar-like separation services instead of procedural • Implementation considerations – No detrimental impact on flight crew – Large network of ground ADS-B receivers
Aeronautics Days, 19 th – 21 st June 2006 Results (2/5) – relatively mature Air Traffic Control surveillance in non-radar areas (ADS-B surveillance) • European R&D projects: NUP-1 & 2, MEDUP, SEAP Maturity scores • EUROCONTROL CASCADE CRISTAL validation trials Operational concept 4 • Australia plan daily 3 Benefits & Transition issues 2 nationwide upper airspace constraints 1 0 coverage by 2007 Systems, HMI & • Capstone Alaska since 2001 Safety Technology • ICAO OPLINK and SASP Procedures & developing separation human factors standards
Aeronautics Days, 19 th – 21 st June 2006 Results (3/5) – medium maturity In-trail procedure in non-radar oceanic airspace (Airborne traffic situational awareness) • Objective: to allow in-trail ADS-B equipped aircraft in non-radar oceanic airspace, which may not be longitudinally separated from each other, to climb or descend through each other’s flight levels. • Benefits: Improved utilisation of the North Atlantic oceanic airspace by facilitating a higher rate of flight level changes yielding better flight efficiency (e.g. fuel savings, increased payload, reduced gaseous emissions, avoiding turbulent flight levels)
Aeronautics Days, 19 th – 21 st June 2006 Results (4/5) – medium maturity In-trail procedure in non-radar oceanic airspace (Airborne traffic situational awareness) • Concept quite stable - RFG draft OSED Maturity scores • Benefits identified • Safety – Operational Hazard Operational concept 4 Analysis on-going 3 Benefits & Transition issues 2 • Procedures – defined in OSED constraints 1 0 and validation on-going Systems, HMI & • Real-time simulations Safety Technology performed for airborne Procedures & human factors • Mixed fleet equipage acceptable
Aeronautics Days, 19 th – 21 st June 2006 Results (5/5) – low maturity Enhanced crossing and passing (ASAS spacing) • Objective: to provide controller with new set of Maturity scores instructions to solve conflicts e.g. directing flight crews to Operational concept 4 cross or pass designated traffic 3 Benefits & Transition issues 2 constraints aircraft while maintaining a 1 0 given spacing value. Systems, HMI & Safety • Immaturity due to similar Technology application in ASAS separation Procedures & human factors being preferred
Aeronautics Days, 19 th – 21 st June 2006 Conclusion • Presented to audience of over 120 at ASAS-TN2 workshop in April 2006 in Rome • Feedback positive – useful for planning priorities • Report available on ASAS-TN2 website (http://www.asas-tn.org) • Notification of 7,000 ATM stakeholders through article in EUROCONTROL Experimental Centre newsletter • Annual updates by ASAS-TN2 in 2007 & 2008
